HYDRO'CARBON-MOTOR.

iai-laces.,

Application filed Elay 10.

fb HN veli/ont 61? may concern lle it known. that l, Jnssn (l. VINCENT, a citt/:eu el the United States, and resident olf Detrein VlVayne county, State olf Michigan, have invented certain new and useful improvements in ltlydrocarbon-Motors, of which the following is a specilication.

This invention relates to hydrocarbon motors and particularly to lubricant battling means.

rl`he principal object oil the invention is to provide baille means coperating with the crank shatt, crank case and cylinders to prevent lubricant `from being thrown by the crank cheeks inte the cylinders while at the saine time the usual amount ot ventilating space around the baille means and lower cud ol1 the cylinifier is maintained whereby any restriction ot the cylinder opening. that would tend to establish an incxi'eased suction in the cylinder behind the piston, is avoided.

lilith this object and others in view, the i n.'ention embodied in preferable term in the construction and ai i ngeinent hereina'iter de :ribed and illustrated in the accompanying drawings, in which:

Figure 1 is an end view partly in vertical cross'sectien of' a motor;

l? ig. 2 is a plan view looking up at the bottom ot the upper halt ot the crank case;

Fig. 3 is a perspective edge view et one ot the baille plates used in the construction; and

llig. l is a similar view ot' another baille plate employed therein.

Referring to the jlrawings, 1() indicates the crank shaft and 11 the crank cheeks or crank arms thereof. '.l`he cylinders are indicated at 12, and 13 are the connecting rods 'for the pistons adapted to operate in said cylinders.

Mounted in the crank case, at each end of said case, is a baille member having horizontal attaching lugs 14; secured to the lflange surrounding the upper half of the crank case, and having a semi-circular flange 15 lying in a vertical plane and extending above the crank shatt but closely adjacent thereto. At its outer edge this lllange carries a curved lateral plate 16 constituting a lubricant throw interrupting element and extendingsemi-eircularly around the crank shaft in the upper haltet' the crank case just beyond the limit ont throw of a crank Specification of Letters atent.

cheek l1. This interrupting element of the baille plates is preferably et at least as great a width as a crank cheek and serves to catch lubricant that may be thrown by the crank cheek in the centrifugal action thereoi1 toward the corresponding cylinder, thus preventing the excessive feed of oil to the cylinder so as to thereby avoid carbonization and undue emission of smoke from the engine through the exhaust. rlfhe baille plate is made of thin sheet metal and owing to this formation and to its location closely adjacent to the crank cheek and at a considerable distance below the lower end of the cylinder, ample ventilation is retained around the baille, and no increase in velocity head ot the air immediately behind the piston is created, thereby avoiding the sucking et oil into the cylinder.

Similar battle members 17 are secured to the bridge piece 1S of the central bearing of the crank case, one on each side of said bridge piece.

Between the end baille members and the central baille members, aremounted in the crank case7 intermediate baille plates 19 which have their ends bent into attaching itlanges 20 adapted to be secured to the walls of the crank case. '1l he side edges et these plates may be iianged at 21 to stillen them. Two oi'f said baille plates are to be employed between each end oi the crank case and the central inaiu bearing, and each of such members extends over a crank cheek and closely adjacent to the upper termination of the travel thereotl and also over the ends of the connecting rod bearings, thus intercepting any oil that leaks out ot these bearings.

ln the operation of the engine, oil thrown by centriitugal torce from the crank cheeks will be carried against the battles and thereby prevented trom entering the cylinders and will fall into the bottom of the crank case.

Having thus described my invention, what l claim and desire to secure by Letters Patent is:

l. In combination with an engine cylinder having an unrestricted open lower end, al crank shaft, a crank case and a laterally extended baille plate mounted in the crank case and extending across the crank case to the side walls thereof and interposed between the crank shatt and the lower end of the cylinder.

2. In combination with a series of engine Cylinders,V a Crank shaft, connecting rods carried by said shaft, and a series ontl laterally extendedV baffle plates mounted on the side walls of the Crank ease above and adjacent to the crank cheeks and spaced from one another and overlapping the bearings of the Connecting rods.

8. In Combination with an engine cylinder, a Crank shaft, a crank shaft cheek,` a

baille plate of semi-Circular form overlapping the Crank Cheek and extending to the end Vof the cylinder and spaced from said cylinder. Y

t. In combination with an engine cylinder, a crank shaft, a crank ease, a curved bathe plate having an attaching iiange and having a laterlly extended interrupting member angularly disposed to said flange and overlapping the crank cheek of said shaft between the same and the lower end of the cylinder.

ln combination with an engine cylinder,` a Crank ease, a crankshaft in said ease and a plurality of baiiie plates extending across said crank ease above said shaft and overlapping the crank cheeks, each plate having its endsiigidly secured to the side Walls of the crank case.

6. In combination with an engine cylinder, a crank case divided longitudinally into two sections, a crank shaft in said Crank ease and a baiiie plate secured to the upper seotion oi' said crank ease, `extending across the crank Case and intercepting the oil thrown upwardly by the crank shaft. Y

In testimony whereof af'ix my signature.
